Hi ,

We have a requirement where I need to consume a flag value returned by the webservice. for the same I have written below code .

 

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(uri);

      WebResponse response = null;

            try

            {

                response = httpWebRequest.GetResponse();

                using (Stream stream = response.GetResponseStream())

 {

                    System.Runtime.Serialization.DataContractSerializer dcs = new System.Runtime.Serialization.DataContractSerializer(Type.GetType("System.String"));

                    bool translation = (bool)dcs.ReadObject(stream);

                    Console.WriteLine(translation);

                    Console.ReadKey();

                }

             }

And when I execute , I am seeing below mentioned exception. Could you please help me in understanding the same and suggest what need's to be done.
